DSecondary emission electron detector set at the focal plane of the VAMOS spectrometer. The inserted spectrum, showing an image of the foreground masque obtained with a 120 Gauss magnetic field, illustrates the spatial resolution
performances of the detector.
The areas of research and development pursued by Sédi are evaluated by its scientific and technical advisory board, which meets annually. R&D programs cover electronics (USB-confi gurable test probe, STUC, for setting up test and capture sets using a PC, FPGA chip
systems), microelectronics (switched capacitor matrix structures), IT (computing grids, multiple-scale transform methods, development and deployment methodologies for real-time software) and detectors (micropattern gaseous detectors, detectors and front-end electronics for CdTe matrices, CMOS active pixels). A study conducted in the field of biomedical instrumentation could also lead to the service’s involvement. Most of these programs culminate
in collaborations with the university or other laboratories of the CEA or IN2P3.
Approximately 12% of the service’s workforce is committed to research and development, enabling it to prepare for the future by maintaining our scientific and technological skills at the highest level.
